Thank you for the review and the feedback, it really helps me!
I am sorry that my plugin caused confusion and an issue with your server. I did not think about these consequences.

The reason I did that:
I wanted to draw attention to the config-file and that the user can easily retrace each option. So someone could count up to 5 and see: "Ah okay, it's 5 seconds and I should raise this value to what I need." But I know that 5 seconds is way too low.

I hoped you would tell me which value fits best but my suggestion:
1) I will raise the value in the default config to 10 seconds.
2) I will add a default message to look into the config so that people can adjust it to their preferred values.

But I still do not know what the issue was on your server. If it is a bug, my plugin has, please get back to me with further information.

In any case I am happy that you enjoyed my plugin nevertheless!
